The main objectives of study were to monitor the metals concentrations, in freshwater fish species, Carassius gibelio and Esox lucius; and to identify any relationships between species and bioaccumulation of metals. The highest concentration of metals (cadmium, 1.96; copper, 24.2; zinc, 49.6; lead, 5.4; chromium, 4.4) between the fish species and tissues was in the liver of Esox lucius, while the lowest (cadmium,0.21; copper,7.2; zinc,19.4; lead,0.9; chromium,0.6 μg/g) found in the muscle of Carassius gibelio. Results showed that the metal concentrations were in fishes in descending order of zinc > copper > lead > chromium > cadmium, similarly in the tissue liver > kidney > gill ~ intestine > muscle.
研究的主要目的是监测淡水鱼类鲫鱼和鱖鱼体内的金属浓度，并确定物种与金属生物积累之间的任何关系。在鱼类和组织中，金属（镉、1.96；铜、24.2；锌、49.6；铅、5.4；铬、4.4）的最高浓度出现在鱖鱼的肝脏中，而在鲫鱼的肌肉中则发现了最低浓度（镉、0.21；铜、7.2；锌、19.4；铅、0.9；铬、0.6μg/g）。结果表明，金属浓度在鱼类中的顺序为锌>铜>铅>铬>镉，在组织中则为肝脏>肾脏>鳃>肠>肌肉。
